You've already seen the very early unboxing of Sprint's upcoming dual-screen Kyocera Echo, and now Wirefly went for an even deeper, more detailed look at the UI itself and all the arguably cool things you can do with such an unconventional interface. The Echo has many people skeptical, but now you can at least try to decide for yourself whether the 2-screen design is a complete gimmick or not. One thing is for sure - if the manufacturer has to include 2 batteries straight in the box, don't expect any world records out of this power-sucker.
